In this study, the temperature evolution, microstructure, and mechanical properties of friction stir welded 80-mm super-thick plate 6082 aluminum alloy were investigated. Combined with numerical simulation and actual measurement, the thermal cycle curve during welding is obtained, and the accuracy o...
